OIL BURNER.

Application filed March 29, 1926. Serial No. 98,214.

The present invention relates to burners, and more especially to burnersusing oil as a. fuel, and aims to provide an improved constructionhaving a reinforcing feature to eliminate defects due to warping, and

also including novel provision for lendingmember so mounted as toembrace the ends of the air supply member to reinforce the same againstwarping tendencies.

ln further carrying out the objects of the invention, l have devised abase casting formed with a suitable supporting flange eX- tendingentirely around the burner structure, and adapted to alford a supportfor the packing construction used around the burner when placed inside alire pot.

With these general objects in view, as well as minor objects as willappear in the course of the detailed description, the invention will nowbe set forth in detail in connection with the accompanying drawingillustrating one form of construction which I have 'devised forembodying* the proposed improvements, after which those features deemedto be n veil will be particularly set ,forth and claimed.

ln the drawing- Figure 1 is al vertical sectional view, .of the lire potportionvof a furnace, and illustratiug in elevation a burnerconstruction embodying the present invention, in its proper relation vto`said lire pot;

Figures 2 and 8 are top and bottom plan views, respectively, of theburner structure;

Figures 4 and 5 are transverse sections, taken on the lines IVIV andV-V, respectively, of Figure 2; and

Figure 6 is a side elevation of the burner structure, taken at rightangles to the view of said burner shown in Figure 1, and a portion ofthe reinforcing ring being broken away.

Referring now to the drawing in detail, this illustrates the improvedburner as comprising a. base or supporting casting 10 of substantiallyring-shape formed with internal slightly upturned flanges 12 for airdefleeting purposes, as hereinafter explained.

The lower margin of said base cast-ing is pr0- ducted to this vided withan outwardly projecting llange 14 to the lower face of which areattached suitable supporting legs l5, necessary for mounting the burnerstructure at the proper height within the fire bowl or `pot 16, as shownin Figure 1. Inpractice, it is also necessary to provide a substantiallyairtight partition between the space around the burner above said flange14, andthe space within the fire pot below said flange," for whichpurpose suitable packingmateriai '1T is spread upon a supporting plate18, Vthe outer margin of which is res-ted upon lugs 19 projecting inwardfrom the fire bowl 16, and, in the present construction, the supportingflange 14 affords a sure and convenient supporting ledge for the innervmargin of this plate 18 and the packing material 17 carried thereby,around the base casting.

lVithin this base casting 10 is mounted the usual burner bowl member 20,the upper and outer margin of which is formed with a ,supporting flange21 resting -upon the upper edge of the casting 10, as clearly shown inFigure 5. The oilsupply is coninlet pipe 22 to the approximatelyconeshaped central porti-on 28 of the bowl, where the oil dischargesupon the upper exterior face of this central portion 23, which in thepresent construction is 'formed with a` spiralchanel `24 extending fromthe top of the portion 28 to the bottom of the 'bowl 2O (see Figures -2and ln this way, a continuous channel is forme-d from the outlet pointof the pipe 22 to the 'bottom of tliei. owl, so that a uniform flow ol"'any oil not immediately vaporized vis lproduced by means of this spiralchannel arrange ment'.

At opposite sides of the burner bowl 2() is formed a pair ofapproximately triangular air intake ports 26 whereby air is conductedfrom below the burner through the base supporting casting 1() and upwardthrough the passages 26 formed within the bowl 20, from which points theair flows into the ends of an arched air supply conduit member 28. Theends or receiving points of this conduit member 28 are alsoapproximately triangular shaped, for fitting over the upper margins ofthe passages 26, as indicated in Figure 4; the eXtreme end edges of theair conduit member 28 project slightly lower than the upper margins ofthe passages 26 into shallow depressions 8O bowl by means of the usuallll cut in the upper margin of the base casting l0, whereby the lattercooperates with the burner bowl member 2O in supporting the air conduitmember, as shown in Figure 6. By this construction, the air employed forsupporting combustion is preheated in the usual manner by being carriedthrough the flame Zone and discharged through an outlet opening 32directly over the oil out let, as seen in Figure Il. Referring to Figure3, it will be noted that the interior flanges l2- of the base casting l0are located on opposite sides of the air passages Q6, the object ofthese flanges 12 being to direct the iow of air from below the castingi() up through said passages 2G; and, in addition, these flanges serveto maintain the burner bowl member 2O in the particular positionillustrated.

rlhe usual oil overflow pipe is provided and connected with the burnerbowl at the 'iro )er Joint for conductino` off anY excess oil. which maybe overflowing therefrom.

n its exterior face, the base supporting casting is formed with a seriesof lugs 34 the upper edges of which form supporting ledges or shoulderspositioned somewhat below the upper marginV of the casting l0 as well asslightly below the base of the depressions 30, as shown in Figure G.These lugs are for the purpose of supporting a reinforcing ring 36 whichis formed with a reinforcing flange 37, the size of this ring 36 beingsuch as to embrace the lower end portions of the air Conduit member 28.rI`hus the ring 36 not only seals the meeting line between the basecasting l0 and the ends of the conduit member, but also serves tostrengthen and reinforce the latter against any warping tendencies underthe influence of high temperatures, which ordinarily cause the airsupply conduit to become distorted and hence to open up air leaks aroundthe joints between it and the rest of the burner, with resul-tantinefficient operation of the burner.

t will thus be apparent that I have devised a practical and efficientburner conn struction for carrying out the desired ob-l jects of theinvention. The flange feature 14 provided in connection with the basesupport-ing casting not only strengthens this portion of the burner, butaffords a positive and permanent support for the packing materialdirectly around the base of the burner. Further, the provision of thereinforcing ring 86 prolonge greatly the life of the burner due to itsprotection of the air supply conduit, and maintains the elliciency ofthe burner for a much longer period than is true of the burners of thisparticular type now in common use.

lVhile I have illustrated and described what I now regard as thepreferred form of embodiment of the invention, I desire to expresslyreserve the right to make all such changes or modifications as mayfairly fall within the scope of the appended claims.

lhat I claim is:

l. An oil burner construction comprising a base casting provided with anexternal supporting flange, packingV material supported by said flange,said cast-ing being also provided with external supporting lugs abovesaid flange, a burner bowl and an arched air supply conduit supported bysaid casting, and an annular reinforcing member supported above saidpacking `by said lugs and embracing the ends of said air supply conduit.Y

2. An oil burner construction comprising a base. casting provided withan external flange, a packing having its inner margin supported by saidflange, said casting being also provided with lugs forming supportingledges slightly below the upper margin of said casting, a burner bowland an arched air supply conduit supported by the upper margin of saidcasting and an annular reinforcing member supported abovesaid packing bysaid lugs and embracing the ends of said air supply conduit.

In witness whereof I hereunto affix myl signature.
